drilling has limits as at some depth the pressures and temperatures force the
drilled opening tight when the drill is lifted.This paper proposes a reliable
and rapid method of penetration of rock masses by melting all or part of the
rock face and penetrate therein, cool the resulting glassy tube to be a
stabilized liner. The methods proposed to heat the tip of the melting element
include heat generated by a micro-thermonuclear reaction. High rates of advance
are sustainable because only heat and cooling water must be advanced to the
tunnel head. The equipment is simple and without need for unduly high pressure
lithofracturing, and the equipment may be regularly removed and switched out to
avoid time and personnel-intensive breakdowns in place. This method can achieve
depths heretofore unreachable to access deep gas, oil, or to create an airtight
and waterproof shaft for geothermic energy.
